Hello, I'm new to the mac world and I am considering buying a 12" PowerBook. I am not a hardcore gamer but I do enjoy playing some games (Unreal Tournament, Starcraft, Deus Ex, Heroes of Might and Magic). I am just wondering if the performance of the laptop will be ok for me. I am currently using a PIII 1GHz with 384mb of ram and a GeForce4MX 440. How do you think the performance would compare?
